Build me a doctor appointment booking website called Appointy.

I want patients to be able to sign up, log in, search doctors by name, specialty, or location, see available 30 minute time slots for a chosen date, book an appointment, and manage upcoming or past visits, including cancelling if needed. Doctors should be able to create and edit their professional profile, set recurring weekly availability, and view and update their appointments. Admin should be able to approve or reject doctors, manage doctors and patients, and see an overview dashboard for appointments.

Please make it a full stack app with a polished healthcare style, responsive on mobile, and include secure login with role based access so patients, doctors, and admin only see what they should. Use a React frontend and a Node, Express, MongoDB backend, and make sure appointment booking prevents double booking on the server. Seed some demo accounts too, and keep the whole thing working end to end.
